s" indicated, to an ice which heattransferirom the outer metallic 1 portions of the article to the inner metallic liner of the article is minimized or reduced as far as possible. r

an article of the character described, in which heat transfer between. portions of the article is reduced to a-minimum, without the use of rubber gaskets and similar devices.

A still further object of the invention provide an article of the character described, in which handles are formed or molded integrally with the aforesaid plastic band, thereby effecting economy in manufacture and assembly of the article, and attaining additional advantages from the standpoint of heat transfer.

O,ther objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a side elevational view of the ice tub Fig. 2 is a top plan view of the ice tub or bucket;

. lifig. 31s a fragmentary cross-sectional view, on

anenlarged scale, taken on the line 3--3 of f s- 2; W Fig.4 is a, fragmentary; cross-sectional View,

,on an, enlarged scale, taken on the line 4-4 of is tothe; ice bucket ortub will be seen to comprise an outer shell i, formed of aluminum or the like, and of generally cylindrical form and provided with a circular base or bottom 2, and an inner shell 3, similarly formed of aluminum or the like, of generally cylindrical form, and likewise provided with a circular base or bottom 4. The upper portions of the outer and inner shells are concentric with each other, while the bases or bottoms 2 and 4 thereof are substantially par allel with each other.

The base 4 of the inner shell has rigidly secured centrally thereof an internally-threaded stake nut 5, to which a screw 6 is secured, the

screw extending through a central opening in the base 2 of the outer shell, a rubber gasket I being interposed between the head of the screw 6 and the lower surface of the base 2. The base 2 has a central raised portion 2a, which accommodates the head of the screw 6.

It will be noted that the inner shell 3 extends vertically to a point considerably above the upper end of the shell I, and is provided with an outwardly extending annular flange 8.

' The upper end of the shell 1 forms a ledge or sill for supporting an annular shelf or band 9, of substantial thickness and molded or formed from a plastic, preferably one having good heatinsulating properties. The shell or band 9 tapers inwardly in its upper portion, which terminates in a downwardly extending, vertically disposed, annular flange Ill, which, at its lower edge terminates-in an inwardly extending, horizontally disposed, annular flange II, the radially-innerdiametrically opposite points of its outersurface with a pair of handles or finger-holds l4 and I5,

which are molded integrally with the band.

The space'between the outer shells i and 9 and the inner shell 3 is filled with fiber glass 16, or similar heat and cold insulating material of light weight.

The ice bucket or tub further includes a lid ,or cover which comprises an upper circular .por-

tion [7 and a lower circular portion l8, both formed of aluminum. The upper portion has a downwardly extending marginal portion i9 which is curved to conform with the curvature of the upper curved portion of the band 9, being seated or disposed in a recess 20 of the band, which is equivalent in depth to the thickness of the marginal portion [9, so that the outer faces of the cover and the band 9 are substantially flush with each other, presenting a smooth and attractive streamlined appearance.

The lower or inner portion IQ of the cover is' spaced from the portion 11 of the cover and has a marginal outwardly extending annular flange 2| which terminates in a vertically-extending annular flange 22 which abuts the inner face of the flange ll of the band 9, when the cover isin closed position, and extends, upwardly-into contact with the upper portion I7 of the cover. The space between the portions I1 and of light weight.

The portion I! of the coverhas a ,centralindented portion 23 above whichfanknobfi'dx of plastic, similar to the plastic of which the band 9 is formed, is mounted. The knob 24 is removably secured to the cover by means of a spacer screw 25, which extends through a cenl8 of the lid or cover is filled with flberx glass or similar heat and cold insulating. material.

placement of the cover on the bucket, but also serves as a ledge for supporting the inner shell and maintaining the latter in spaced relation to the outer shell.

It is to be understood that the form of our invention, herewith shown and described, is to be taken as a preferred example of thei same, and

that variouschanges in' the shape, size and arrangement of parts may be resorted to, without departing from the spirit of our invention, or the scope of the subjoined claim.

" In-ice-bucketsor-tubs of this type, in whichzthe outerand inner shells are formed entirely of metal, there is atendency for heat from the outside'atmosphere or from .the:surf'ace.on whichzthe bucket. is supported to be transmitted: from? the outershell toithe. innershe-ll'through the joint between: the,lidor cover-and the-bodycf thetbucket, which heat causes melting. oftheice: cubes: in the bucket ina' fairly short-period oftime. This is due principally to thezfact that there is virtually arcontinuousior unbroken metal to-metal contact at this joint. This tendency is counteracted; to a slight extent, by the use of rubber gaskets or the like at-the joint, but these; gaskets are objectionable-mice gucketsor the like, sincethey not only. impart an'objectionabletaste to the cubes,

but also: constitute anuisance in that they are diiflcult to maintain in place, and must be kept in a sanitary condition;

Bythe useof a plastic band9, of the general construction shown, as a part of the outer shellof the bucket-or tub, a numberof distinct advantages are: obtained.

In the first place, the metal to' metal contact at the joint isbroken up by'the interpositionof a material which is an' extremely poor; conductor of; heat, so thattransmission of heat from the shell l and cover to the inner she1l3 isreduced to a minimum, thereby preserving-the. ice cubes againsttoo rapid melting.

In the second place, the use of gaskets-at'the joint'between. the-cover. and body of the bucket iseliminated, thereby overcoming the disadvantages incident to the useof such gaskets.

In ,thethird place, since the handles l4 and-l5 are formed integrally with thebandS, thecost of manufacture and assembly is reduced to a considerable extent, fastening devices at .these points are eliminated, a more sanitary condition is maintainedatthesepoints due to the easeoi cleaning, andfthepossibility of heat transfer to the inner shellfrom the hands during handlingorlifting of the bucket is also eliminated.

As a further advantage, the plastic ring or bandserves, not-only tocenter and facilitate Having thus described our invention, we claim: In; anarticle ofzthe character described, an outer: metallic: shell, and an annular insulating "plastic band ofi'substantial thickness supported upon the upper'edge of the outer shell and forming, acontinuation thereof with the lower outer wall of the band recessed to a depth equivalent to-a thickness of the outer shell for the reception of the upper end of the outer shell in flush engagement therewithwherebythe outer: surface of the outer shell is flush with the outer Surface of they bandto form a smooth outer surfacefor said artiele said band having an. integraldownwardly turned flange terminating in an annular flange extending radially'inwardlyto a point adja-cent the upperv end of the inner; metallic shell, the inner shell having a radially outwardly extending flange .supportedonand directly" engaging the annular flangeof the-band andameans securing; saidv innerand outer. shells together thereby holding said band-onsaid outer shellby means of the flange on the inner shell and. a metallic cover having a projectinglip; resting on said plastic zband withthelower edge of the cover being in' spaced relation to the annular flangeof said band. and the flange on the; inner shell there'- by forming an'air-gap therebetween, whereby, the cover is insulated from said inner and outer shells, said band having airecess'in its upper edge receiving; the lip on-said cover and lying flush with the outersurface'of the cover.
